Both Gas- and Steam to power EV battery range?

Nick Kurczewski is writing about extremely small (gas) turbines, which can extend the travel range of electric cars in his blog on the website of Green Car Advisor. He’s talking about the Dutch company MTT en the Israeli Company EVT Motors, but he forgets to mention Green Turbine BV. Although Green Turbine is mostly suitable for hybrid cars (the turbine can use the waste heat of the motor), it also can be used in electric cars with a gas turbine, because waste heat of a gas turbine can be used to drive Green Turbine.

So, what exactly is the Green Turbine?  Well, it’s a small (slightly larger than a football), lightweight and silent micro steamturbine with an output in the range of 1-15 Kw. It converts steam to electricity and also produces heat in this process. It can be driven by any fuell type (natural gas, propane etc.), waste heat, biomass and fuel cell.

The turbine has been developed in the past five years by a small company called Green Turbine BV (it has also a Canadian version which is the company Green Turbine INC. info@greenturbine.net

Green Turbine is not developing a prototype, it actually has a working prototype. The only thing left, is the long term testing which is starting at the end of October.

Green Turbine can extend the efficiency of hybrid cars by 20-30%. As previously mentioned, it captures the waste heat of the engine exhaust and converts it into electricity. We calculated this percentage based on the following:

In hybrid or fuel cell cars about 10% of the waste heat can be recovered and converted to electricity. As waste heat is about 75% of the total energy input of a car, this 10% is substantial. It will boost total efficiency of a hybrid automobile between 20 – 40%.

Imagine what Green Turbine could do in an electric car, when it is placed after a gas turbine!
